BREAKING CHANGE: Library now requires system-installed dependencies Major Changes: - Convert secp256k1 from bundled static lib to system dependency - Convert OpenSSL from bundled static lib to system dependency - Convert curl from bundled static lib to system dependency - Update build.sh with pkg-config detection and fallback logic - Remove all static library extraction/building logic - Update README.md with new dependency requirements and installation Build System: - Add detect_system_secp256k1() with pkg-config support - Add detect_system_openssl() with pkg-config support - Add detect_system_curl() with pkg-config support - Remove secp256k1 building/extraction from ar archive - Update CFLAGS and LIBS to use system library variables - Clear error messages for missing dependencies with install commands Documentation: - Add system dependency installation for Ubuntu/Debian/CentOS/macOS - Update all compile/link examples to include -lssl -lcrypto -lcurl -lsecp256k1 - Remove references to 'self-contained' and 'no external dependencies' - Update integration examples throughout README Benefits: - Smaller library size (only internal code bundled) - Automatic security updates via system package manager - Standard Linux library distribution pattern - Reduced build complexity - Better system integration with pkg-config Required Installation: Ubuntu/Debian: sudo apt install libssl-dev libcurl4-openssl-dev libsecp256k1-dev CentOS/RHEL: sudo yum install openssl-devel libcurl-devel libsecp256k1-devel macOS: brew install openssl curl secp256k1
